731bd0f345 If a non-liquid liquid solution is found, bump up the liquid density and try again 
Ok, this isn't perfect, but it seems to work pretty well.

86f52bdf4e Phase Envelope calculations now include Tsat_max and psat_max, along with indices thereof. 
The Tsat_max and psat_max values are calculated using exact solution based on finding dT/dP and dp/dT equaling zero by a 1D solution in rhov.
